703 Running th e line – Importan t Factors
Most Important Factors – Line Downtime
Results –Lost Production Output
Tasks that can cause a high Downtime
Not refilling empty reels – feeders run out of components.
Incorrect splicing of tapes – feeders jam and have errors.
Operations Success Measures
Number of machine stops / shift due to feeders running empty.
Number of machine due to feeder jams or errors.
Operations Target
Zero machine stops due to feeders running empty!
Zero machine stops due to feeder jams or errors!

Line Down time
Important Factors for Keeping the Line Running
1. Do not allow component reels to run empty!
2. This error message should not be seen!
Most Important Factors – DPM, MFR, Scrap Rate
Results – Lower Quality, Rework Costs, Higher Production Costs
Tasks that can cause quality Problems
Loading incorrect parts onto feeders / MTC

DPM = Defects per million – a measure of how many parts are misplaced or not placed at all.
MFR = Material Failure Rate – how many PCBs fail at test.
Number of incorrect parts loaded / shift
Operations Target
Zero incorrect components loaded!
Most Important Factors – DPM, MFR, Scrap Rate
Results – Lower Quality, Rework Costs, Higher Production Costs
